Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Source text:
Elizabeth was born on 21 April 1926, the first child of Prince Albert, Duke of York (later King George VI), and his wife, Elizabeth, Duchess of York (later Queen Elizabeth The Queen Mother). Her father was the second son of King George V and Queen Mary, and her mother was the youngest daughter of Scottish aristocrat Claude Bowes-Lyon, 14th Earl of Strathmore and Kinghorne. She was delivered at 02:40 (GMT)[1] by Caesarean section at her maternal grandfather's London home, 17 Bruton Street in Mayfair.[2] The Anglican Archbishop of York, Cosmo Gordon Lang, baptised her in the private chapel of Buckingham Palace on 29 May,[3][b] and she was named Elizabeth after her mother; Alexandra after her paternal great-grandmother, who had died six months earlier; and Mary after her paternal grandmother.[5] She was called "Lilibet" by her close family,[6] based on what she called herself at first.[7] She was cherished by her grandfather George V, whom she affectionately called "Grandpa England",[8] and her regular visits during his serious illness in 1929 were credited in the popular press and by later biographers with raising his spirits and aiding his recovery.[9]

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Source text: The Eiffel Tower is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It is named after the engineer Gustave Eiffel, whose company designed and built the tower. Constructed from 1887 to 1889 as the entrance arch for the 1889 World's Fair, it was initially criticized by some of France's leading artists and intellectuals for its design, but it has become a global cultural icon of France and one of the most recognizable structures in the world. The tower is 324 meters tall, about the same height as an 81-story building, and during its construction, it surpassed the Washington Monument to become the tallest man-made structure in the world, a title it held until the completion of the Chrysler Building in New York City in 1930. The Eiffel Tower is the most-visited paid monument in the world; 6.91 million people ascended it in 2015. The tower has three levels for visitors, with restaurants on the first and second levels. The top level's upper platform is 276 meters above the ground – the highest observation deck accessible to the public in the European Union. Tickets can be purchased to ascend by stairs or lift, with the stairway initially having 1,710 steps, although it is usually possible to take the lift from the second level to the top.
